On Carnival ships, the pizzeria is open 24/7, as is the softserve ice cream area. At the pizzeria, you can get a Caesar salad - which would tide you over nicely until your 8:30 dinnertime. Also, from room service, you could order the Crudites w/Bleu Cheese sauce. Nothing like a few veggie sticks to stop the hungers. And yes, "tea" is a nice way to shake off the hunger attacks, with the little cakes and finger sandwiches. On Carnival, there is ALWAYS something to eat!
